To all 'whom t may concern:

Be it known that I, FREDERICK I-I. GIBBs,

y residing at New York city, New' York, and

- ments in Car Construction, of which the following is a full, clear,and exact description, such as will enable others skilled in the art towhich it appertains to make and' to use the same, referencefbeing had tothe accompanying drawings, which illustrate the preferred form of theinvention, though it is to be understood that the invention is notlimited to the exact details of also showing supporting bolster and sideposts of conventional design. Fig. 2 is a view similar to Fig. 1,showing a slightly modified form of construction. Fig.v 3 is anothermodified form, showin a. door operating shaft beneath the shed ingportion. Figs. 4, 5 and 6 are similar views showing slightly differentand modified forms. Fig. 7 is a reduced plan view looking'down upon asection of the car constructed in accordance with my invention.

This invention -relates to side wall constructions for dumping cars, andcomprehends in its adaptations the simplification of assemblages, thebracing of the shedding `portion of the side wall and the utilization ofthe space beneath theshedding portion for some of the operativemechanisms controlling the doors and other devices.

A further object of the invention is to provide a substantial holdingmeans for bracing the lower end of the side plate from the underframe,or other substantial part of the car.

Referring to the parts: F is a body bolster or other cross-bearer, H is'a side wall of the car bent inwardly at its lower portion andterminating above the body bolster or crossbearer F. l

G is a yrelatively Z-shaped connecting plate or casting uniting the bodybolster or cross-bearer F with the lower edge of the inclined portion ofthe side wall.

Heretofore attempts have been made to provide a shedding surface for usein gondola cars in which the plate metal forming the side wall was bentinwardly, then bent outwardly parallel with the top ed e of thecross-bearer and downwardly at t e outer end of the bolster orcross-bearer, the bottom portions of the side wall being respectivelyhorizontal and vertical, and being 4used as connecting means for theholsters and intermediate cross-bearers of the car underframe. This typeof construction has numerous disadvantages, among which may be notedthat the entire side sheet must be manipulated to provide the V-shapedbottom portion, as well as thevertical flange. There are additionaldisadvantages owing to the weight and size of large sized sheets nowused to form theside walls of gondola cars.

As a further disadvantage it is noted that in those constructions inwhich the horizontal and vertical iiange portions are integral with theside walls it is frequently necessary to use supplemental braces, due tothe thinness of the metal forming the side sheets.

To overcome the above outlined diiiiculties, the present invention isproduced, in which the member indicated by the letter G is preferably,formed of pressed sheet metal, or may be made in the form of a casting.When made of pressed sheet metal, it is usually constructed of metalstronger and thicker than the side sheets I-I. With the sheet metal themembers G may be flanged by a simple die, comprising male and female dieportions, with guides provided at the sides of the female die to insureproper alinement of the angles of the vertical and oblique anges,characterizing, devices of this character. With this construction theconventional underframe may be used, comlprising cross-bearers andholsters, with either single or double center sills, and the pressingsor castings G may be placed in position above `the bolster Cover plateI, resting on the horizontal Han es B of the bolster, and securedthereto y vertically disposed rivets B', and secured to the vertical endflanges of .the bolster by horizontally disposed rivets S, which rivetsalso extend through the outstanding anges of the side 2.

p0lsty using metal pressings G with vertical dan 3 and oblique flanges4, a rigid connection is rovided between the side sheets of the car bodyand the bolster, which is of muchy greater strength than would bepracticable 1f this connection were formed by a horizontal extension ofthe side sheet. It is levident that a relativelynarrow plate, such aswill be required to form the member G, can be pressed to form with lesstrouble and expense than if the entire side sheet of the car is bent tothe form of the plate G, and it is also evident that it would becommercially unprotable to form side sheets of the car of a thickness ofmetal which is found necessary for use in constructing the member G. y

An additional feature of advantage in the angular `memberG is that itmay be utilized as a su port for door operating elements commonll;remployed to lift or to lift and lock the drop doors usually carried bycars of this construction. When the member G, or some modification ofthe same, is used to support the door actuating members, it is usuallysupported directly from the transverse members of the underframe.

With link and crank arm devices used for lifting such doors, it ispreferred that the member G shall be relatively narrow transverselyv ofthe car, and may be offset outwardly at intervals along its obliqueinner flange to provide a clearance between such flange and the inclinedlower end of the side plate forpassage therethrough of the door liftingmeans.

' Where winding shaft and chain lift is employed, as in Figs. 3 and 6,the member G may be perforated at intervals, asshown at 10, in Fig. 7for the passage therethrough of a winding chain adapted to wind on theshaft 8, shown in Figs. 3 and 6, although it is to be understood that asimilar shaft may be supported above any of the modified forms of platesherein disclosed. When liange 4 of the member G the chain is used theplate G is pre'ferably wider, and may be provided with a corrugationembracing the shaft 8, a corrugation 9, acting as a shoulder, againstwhichI the shedding surface rests and the oblique overlapping flange 4fastened by means of rivet 12 to the lower end of the sheet H.

'It is further noticed that the oblique may be extended to`provide spacefor one or more rows of rivets connecting it to the inwardly disposedlower portion of the side sheet H, or its lian e 6 may be formed, asshown in Fi .3, outside of the shedding surface H, the sledding surfacebeing extended downwardly to bear within the angle, as shown in Fig. 4.The 'ange 4 may be positioned beneath the l wall lapping transversemembers,

oblique portion of the sheeting H, and the angular plate 15 may have oneportion disosed beneath the member G and disposed tween the member G andthe bolster F, and have an inclined portion 16 overlapping the loweredge of the sheeting H and the flange 6. `By these constructions it isnoted that the member G is of greater thickness than the side sheeting,forming in eifect a side sill having a vertical flange and an obliqueflange, and with a separate web portion horizontally disposed for thegreater portion of Aits width.

e the member G has been referred to as a side sill or sheeting, it is,of course, to be understood that the side of the car dis closed is aplate girder preferably provided with the'usual compression flanges atthe top, but, if desired, the member G may be utilized as a side sillformed as a truss and lined by metal sheeting, as is common in fthe oldwood car.

frame members; a Z-shaped side sill of relatively thick metal connectingsaid members, said sill having an oblique ange, posts connected withsome of said transverse members, and a sheet metal side wall terminatingabove said transverse members and of less thickness than said sill andsaid s ide said oblique ange and being connected respectively with saidposts and oblique flange.

2. In a car construction, transverse members, a vertical side wallprovided with inwardly bent lower portion terminating above saidtransverse members, side osts, and a relatively Z-shaped` member with ahorizontal web portion between said wall and transverse members,connecting a plurality of said transverse members and having an inclinedflange connected to the lower portion of the side wall.

3. In a car construction, a plurality of a side wall, 'a part of whichis in relative vertical alinement with the ends of some of said membersand which is provided with an oblique lower end portion terminatingabove said transverse members, a side s ill having a horizontal web andobli ue flan e resting on the transverse mem rs an connecting aplurality of the transverse members and connected directly to saidoblique lower end of the side wall.

4. In a car constructed with sheet metal3v de walls having a verticalportion and an web portion secured to and connecting a plurality of saidcross-bearers having an oblique flange lapping and being connected tosaid inwardly inclined Wall portion whereby the load shedding portion ofthe wall is reinforced and connected with said cross-bearers.

5. In a car constructed with sheet metal side walls having an inwardlyinclined load shedding portion, an underframe comprising a pluralityy oftransverse members, a relatively Z-shaped member with horizontal web andinclined flange vextending parallel with the inclined kportion of saidwall and connected thereto, the horizontal web of said Z member beingconnected with the top and ends of a plurality of said transversemembers.

6. In a dumping car, the combination comprising a cross-bearer, a sidewall extending over a portion of the cross-bearer, a

plate connected with said wall and crossbearer and a door lifting shaftresting on said plate.

7. A car wall comprising a relatively large thin sheet having its lowerside bent inwardly'to form a shedding surface and a separate relativelyhea connecting plate of substantially Z-shape 1n cross section lappingand being fastened thereto and constituting the lower portion of saidshedding surface.

8. In a car, a side wall vertical for a portion of its depth and obliquefor another portion, transverse underframe members, posts connected withsaid wall and members, a Z-shaped plate lapping the oblique portion ofsaid wall and connecting said transverse underframe members, and a shaftabove said members between the posts and said wall.

9. In a car, a wall comprising a sheet of metal vertical for a portionof its depth and inclined inwardly of the car near its bottom, aplurality of posts connected to said vertical portion, a Z-shaped lateconnecting said sheet with all of sai posts, and a winding shaft betweensaid post and the inclined portion of said wall.

10.
